Beyond 3G: new standards
Specifications for next-generation mobile technologies – IMT-Advanced – have been agreed on at the ITU Radiocommunication Assembly currently meeting in Geneva.
Following a detailed evaluation against stringent technical and operational criteria, ITU has determined that "LTE-Advanced" and "WirelessMAN-Advanced" should be accorded the official designation of IMT-Advanced.
IMT-Advanced systems include new capabilities that go beyond IMT-2000, widely deployed since 2000 and referred to as 3G mobile technologies. ITU has now specified the standards for IMT-Advanced, the next-generation global wireless broadband communications that provide access to a wide range of packet-based telecommunication services supported by mobile and fixed networks.
ITU Secretary-General Hamadoun Touré hailed the announcement as a landmark development in mobile technology. “IMT-Advanced marks a huge leap forward in state-of-the-art technologies, which will make the present day smart phone feel like an old dial up Internet connection. Access to the Internet, streaming videos and data transfers anytime, anywhere will be better than most desktop connections today.”
François Rancy, Director of ITU’s Radiocommunication Bureau, said: “IMT-Advanced would be like putting a fibre optic broadband connection on your mobile phone, making your phone at least 500 times faster than today’s 3G smart phones. But it’s not only about speed; it’s about efficiency. IMT-Advanced will use radio-frequency spectrum much more efficiently making higher data transfers possible on lesser bandwidth. This will enable mobile networks to face the dramatic increase in data traffic that is expected in the coming years”
IMT-Advanced systems support low to high mobility applications and a wide range of data rates in accordance with user and service demands in multiple user environments. IMT-Advanced also has capabilities for high quality multimedia applications within a wide range of services and platforms, providing a significant improvement in performance and quality of service.
Over the last 25 years, ITU has developed the IMT framework of standards — or International Mobile Telecommunications system — for mobile telephony and continues to lead international efforts involving governments and industry players to produce the next-generation standards for global mobile communications.
